Patented Oct. 1 2, 1943 UNITED STATES PATENT OFFICE I SCRAPER MangerHansen, Freeport, N. Y. Application August 26,1942, Serial No. 456,282 2Claims. (01. 30-171) My invention relates to scraping tools, and hasamong its objects and advantages the provision" of animproved hand tooldesignedto facilitate the scraping of floors, stair structures, trim andthe like, particularly in corner formations and recessed contours suchas are present in practically all door and window frame structures.

In. the accompanying drawing:

Figure l is a face view of a hand tool in accordance with my invention;

Figure 2 is a sectional view along the line 22 of Figure 1;

Figure 3 is a face view of a scraping blade;

Figure 4 is a face view of a modified form of scraper blade;

Figure-dis a face view of another form of Figure 6 is a sectional viewalong the line 66 of Figure 5; and Figure '7 is a sectional view of adifferent form of scraper blade wherein the blade unit is provided withoppositely inclined scraper edges.

In the embodiment selected for illustration, I make use of a wood handleIll contoured with a grip formation l2. This handle is substantiallystraight throughout its entire length and is provided with a flatblade-supporting face l4.

To the face [4 is clamped a scraper blade l6 through the medium of abolt l8. This bolt is provided with a square body 20 fitting snugly in asquare opening 22 in the handle ID, as well asin a rectangular slot 24in the scraper blade l6. Thus the bolt 20 is restrained from rotation,and the scraper blade l6 may be adjusted a limited distancelongitudinally of the handle l but is restrained from rotation about theaxis a handle engaging flange 32 of considerable diameter. Thustightening of the nut 30 clamps the blade l6 and the'handle Ill into aunitary structure.

The blade I6 isprovided with a scraper flange 34 at one end thereof andsharpened to a cutting edge 36. This flange is arranged at right anglesto the longitudinal axis of the scraper blade I and is of slightcurvature.

the scraper blade I6, as illustrated in Figure 2. With the scraper bladeIS in the operative position of Figure 2, the flange 38 projects beyondthe end of the handle in, with the flange 34 The other end of thescraper blade I6 is formed with a semicircular flange 38 which tapersinto the plane of lying some distance inwardly of this end. of thehandle. Eitherflange 34 or 38 may be employed by merelyloosening thebolt 18 and turning the Q scraper blade to the desired position. A sharpcutting edge 40 is also provided on theflange' 38. ,f

The scraper blade 42 of Figure 4 differs from that of Figure 3 only inthatboth flanges44'are of semi-circular contour. In Figure 5, thescraper blade 46 differs from the scraper .blade l6 only in that'the twoflanges 48 are character-. ized by slight curvatures along'the lines ofthe flange 34, with the flanges 4'8 bentto angular positions slightlyless than right angles with re spect to the plane of the scraper blade46.}

In thescraper blade of Figure '7, the flanges 50 project from thescraper blade 52 in opposite directions. In employing the scraper blade52,

it is necessary that the handle l0 have a formation shaped toaccommodate one of the flanges'f 50. A hand tool in accordance with myinvention employs a relatively small amount of metal. The\ scraperblades are designed to scrape paint, varrush and the like in placeswhere conventional, scraping tools are not accessible. The relativelystraight cutting flanges are suitable for corner and flat surface work,while the semicircular flanges operate effectively in 'concaved groovesand curved formations.

Without further elaboration, the foregoing'will so fully illustrate myinvention; that others may,

by applying current knowledge, readily adapt the same for use undervarious conditions of service. a

I claim: 1. A scraper tool comprising a handle, a blade of narrowelongated formation arranged on the handle with an end portion thereofextending forwardly beyond the handle, the blade being provided at itsforward end with a scraper flange of substantially semicircularformation in plan and tapering towards its ends into the plane of theblade, substantiallythe entire portion of the blade extending forwardlybeyond the handle, and a bolt securing the blade to the handle, vthebolt passing through said parts and provided with a polygonal portionengaging said parts to hold them against turning movement-one withrelation to the'other. v I I l 2. A scraper tool comprising "a handle,ablade arranged 'on the handle withan end portion,

- thereof extending forwardly beyond the handle, the blade beingprovided at its forward'en'd with a e a scraper flange of substantiallysemicircular I formation in plan and tapering towards its ends into theplane of the blade, the .entire scraper flange extending forwardlybeyond the handle, 7 and means securing the blade to the handle.
